ing;r at Chicago, in lie county of Cook sind.A

Sitz/ite of illinois, have invented e certain new end nsefliiimprovemeniin Door-@pen ating Mechanism for Refrigerator-Gers and thelike, of which the following is a nii, eoneise, end exact description,ren erence being had to the accompanying firewings, forming e. peri, ofthis specification.

Thil@ invention relates to improvements in doei" operating mechenismiorrefrigerator cere and eine like.

An object of the .invention is to provide o. door operetinginechonismfor reii'igei'aioi eers Wheifein time shaft of thef'mechenism ie given erolling movement prvellel with lie ieee of the door, enel wlieijeinmeans eye provided; for lifting the shaft- So that she lower endeiiei'eof may lie raised flush with the lower edge of" the door,end'thue per'- init the ieei io loe ieafiily swung out over epieinfoin.. n

,in orden to Joli ''.iie eiinfe e; infami lever 29 provided which iepivotefi to the e. eingle piece casting;

since ehe gein: piece 15 iin accordance lGO Vby the inter-engagement ofthe shaft as indicated at 30, the lever 29 'being 'forked andstraaldling the shaft as side of the shaft, but when the lever is swungthrough an are of 180C to the position shown inl Figs et, 5 and 6, is onthe inner side of the shaft. This cam 31 is adapted `to cooperate with anlcruin castinp 32hav- .ing a. curved depression or notched member 33,said casting 32 having also an npstanding guide flange 34:.

The operation is as follows: Assuming* the parts in the position shownin Fig. l, the door is opened by g 'asping the lever 29 and swinging itthrough an arc of 180. This causes the shaft A to'both rota-te and roll,the latter movement being occasioned gears and racks. As this rolling ofthe shaft takes place, the cylindrical ends 18H18 will travel np theinclined cammino' surfaces 23 of the keepers and thus :torce `the doorlll. open to thedotted positionshown in Fig. 7.

If it is now desired to lift the shaft -so that the lowercylindrical endi8 will clear an adjacent platform as indicated at 40 in Fiel 5l, thehand llever 29 is depressed, the cam 3l engaging the fulcrurn casting'and thus lifting the shaft A. The depression 33 is so arranged that thecam 3l will `fall ther-cinto when the lever 29 is depressed. And il'y islocated directly beneath the axis of the pir@ otal connection betweenthe hand lever and shaft. With this arrangement, after the shaft hasbeen elevated, it will automatically be retained in such elevatedposition, due to the weight of the lever 29 in its depressed or downwardposition. To close the door, the reverse of the above described sequenceof operations is employed, toe door being forced to closed position bythe cylindrical ends 18 engaging the inclined cannning surfaces Q4 ofthe keepers.

Although l have herein shown and described What .l now consider thepreferred embodiment of my improvei'nents, vet l a in aware 'thatchanges and. modilications may,7 be made without departing from thespirit ci* the invention, and l contemplate all such changes and.modifications as come within the scope of the claims appended hereto.
